UVM_CMDLINE_PROCESSOR working issue

mahee424

Hi,

  I'm trying to get value from command line using UVM_CMDLINE_PROCESSOR but couldn't extract the value from command line with the following trail code;

class onscl extends uvm_object;

    extern function new(String name="onscl");

endclass

function onscl::new(string name = "onscl");
     uvm_cmdline_processor l_cmd = uvm_cmdline_processor::get_inst();
     string onscl_inputs[$];
    

     super.new(name);

     void'(l_cmd.get_arg_values(.match("+LENGTH="),.values(onscl_inputs)));
     foreach(onscl_inputs[i])

     begin

        `uvm_info(get_name(),$psprintf("ONSCL-INPUTS[%0d]:%s",i,onscl_inputs[i]),UVM_LOW)

     end

endfunction

       Please share your suggestion  for getting variable value from command line.

Regards,

mahee

  • Having the same issue,couldn't extract the value from command line with flowing code ,

    function void start_of_simulation_phase(uvm_phase phase);
    int num; 
    uvm_cmdline_processor clp; 
    string myarg ;
    clp = uvm_cmdline_processor::get_inst();
    num = clp.get_arg_value("+myarg=",myarg);
    if (num)
    begin
        $display("****************");
        $display("STRING=%0s",myarg);
        $display("****************");
    end
endfunction

    Works for me:

    // clp.sv
    `include "uvm_macros.svh"
    module clp;
    import uvm_pkg::*;
    class clptest extends uvm_test;
    `uvm_component_utils(clptest)
    function new (string name="clptest", uvm_component parent=null);
    int num;
    uvm_cmdline_processor clp;
    string myarg ;
    super.new(name,parent);
    clp = uvm_cmdline_processor::get_inst();
    num = clp.get_arg_value("+myarg=",myarg);
    if (num)
    begin
    $display("****************");
    $display("STRING=%0s",myarg);
    $display("****************");
    end
    endfunction
    endclass
    initial run_test("clptest");
    endmodule

    % xrun clp.sv -uvmhome CDNS-1.1d +myarg=abcd

    Make sure that you do not have the "-define UVM_NO_DPI" or "+define+UVM_NO_DPI" enabled. These will disable the Command Line Interface.
